Rhine Franconian (German: ), or Rhenish Franconian, is a dialect family of West Central German. It comprises the German dialects spoken across the western regions of the states of Saarland, Rhineland-Palatinate, and Hesse in Germany. It is also spoken in northeast France, in the eastern part of the département of Moselle in the Lorraine region, and in the north-west part of Bas-Rhin in Alsace. To the north, it is bounded by the Sankt Goar line (“das/dat line”) which separates it from Moselle Franconian; to the south, it is bounded by the Main line which is also referred to as the Speyer line which separates it from the Upper German dialects.
